Butyl rubber plug good air tightness, good heat resistance, good acid and alkali resistance, good internal cleanliness,

Butyl rubber stoppers contain isobutylene and a small amount of isoprene (< 3%) Synthetic rubber polymerized under ultra-low temperature (-95 degrees Celsius), its unique chemical stability, excellent sealing to ensure the quality of drugs, improve the safety of drugs, but also reduce the natural rubber plug production required for the wax hot process, pad and polyester film process. Butyl rubber stopper is much better than natural rubber stopper in product standard, production level, performance, product quality and so on.

The infiltration of gas and water vapor in the storage process of the medicine after the bottle stopper is extremely harmful, which is the main reason for the deterioration of the medicine.

Due to the characteristics of molecular structure, butyl rubber plug has tight structure, less hydrophilic impurities and low water absorption.
